OBJECTIVES: To evaluate and characterise articular cartilage degeneration in patients with osteonecrosis of the femoral head (ONFH) using T2 mapping magnetic resonance imaging (MRI). METHODS: We reviewed 35 patients with ONFH (20 males and 15 females, mean age 45.7±12.9 years) without obvious cartilage abnormalities on plain MRI (ONFH group) and 25 healthy volunteers (9 males and 16 females, mean age 42.9±5.8 years) (control group). All patients underwent T2 mapping MRI after ONFH onset...

Preeclampsia (PE) is a pregnancy-specific disorder and a major contributor to maternal and fetal morbidity and mortality. Role of oxidative stress in early pregnancy with the pathophysiology of the disorder is unclear. The current study aims to analyse maternal levels of oxidative stress markers (MDA and protein carbonyl) longitudinally across gestation and placental levels of oxidative stress markers (MDA, protein carbonyl and 8-oxo-2'-deoxyguanosine) in women with PE and compare them with non-PE women. 324 pregnant women (216 non-PE and 108 PE women) were longitudinally followed during pregnancy...

Acute promyelocytic leukemia (APL) stands out as a distinctive form of acute leukemia, exhibiting a higher occurrence of thrombotic events when contrasted with other leukemia subtypes. Since thrombosis is a relatively rare but unfavorable condition with poor prognostic implications, it is crucial to determine the risk factors for thrombotic events in APL(thrombosis in large venous or arterial from onset to differentiation therapy in 30d). We performed a retrospective study involving 950 APL patients between January 2000 and October 2022, from which 123 were excluded by younger than 16 years of age, 95 were excluded by incomplete data, and 6 were excluded by thrombosis related to CVC or PICC...

Adherent and invasive Escherichia coli (AIEC) is a pathobiont that is involved in the onset and exacerbation of Crohn's disease. Although the inducible expression of virulence traits is a critical step for AIEC colonization in the host, the mechanism underlying AIEC colonization remains largely unclear. We here showed that the two-component signal transduction system CpxRA contributes to AIEC gut competitive colonization by activating type 1 fimbriae expression. CpxRA from AIEC strain LF82 functioned as a transcriptional regulator, as evidenced by our finding that an isogenic cpxRA mutant exhibits reduced expression of cpxP , a known regulon gene...

OBJECTIVES: Autoimmune encephalitis (AIE) is a group of rare, increasingly recognized, potentially reversible, noninfectious causes of unexplained encephalitis. It affects any age-group and has a plethora of clinical presentations, the most common being the neuropsychiatric manifestation. The diagnosis of this entity at the right time and proper treatment with immunotherapy can save many lives. In this study, we describe the demographic profile, clinical spectrum, diagnosis, and treatment of 42 patients with features of AIE...

AIMS: Despite ischemic stroke having much importance as one of the top 10 causes of death in older women, there is limited data on age at menopause and ischemic stroke. We performed a systematic review and meta-analysis to estimate the effect of age at menopause on ischemic stroke. METHODS: We screened four databases (PubMed, Cochrane, Web of Science, and EMBASE databases) up to July 17, 2023. This systematic review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and was registered with PROSPERO (CRD42023444245)...

Objective : This study aims to delineate the characteristics of severe self-injurious behaviors (SIB) in a cohort of children with autism and unspecified intellectual developmental disorder (UIDD) (intellectual disability) and examine potential risk factors for developing SIB. Methods : A retrospective chart review studied characteristics of severe SIB in 30 children with autism spectrum disorder (ASD) and UIDD referred to a tertiary care center. Characteristics examined include genetic syndromes, brain MRI abnormalities, verbal ability, adaptive functioning, SIB frequency and severity, age of onset, number of psychopharmacological agents, irritability, hyperactivity, stereotypy, psychiatric and physical comorbidities, among others...

Previous studies have explored cognitive disabilities experienced by autistic children between the ages of 2 and 5 who attend special schools. However, there is still debate regarding the onset, scope, and causes of these problems, particularly when considering incarnate biases that may arise from affective notions. Early affective issues could potentially be a key factor contributing to observing such biases in picture captions. In this study, we employed an affective approach-simultaneous observation and questionnaire-to investigate how incarnate biases impact picture caption activities...

Identifying individuals with early stage Alzheimer's disease (AD) at greater risk of steeper clinical decline would allow professionals and loved ones to make better-informed medical, support, and life planning decisions. Despite accumulating evidence on the clinical prognostic value of tau PET in typical late-onset amnestic AD, its utility in predicting clinical decline in individuals with atypical forms of AD remains unclear. In this study, we examined the relationship between baseline tau PET signal and the rate of subsequent clinical decline in a sample of 48 A + /T + /N + patients with mild cognitive impairment or mild dementia due to AD with atypical clinical phenotypes (Posterior Cortical Atrophy, logopenic variant Primary Progressive Aphasia, and amnestic syndrome with multi-domain impairment and age of onset < 65 years)...

Background : Immune reconstitution following the initiation of combination antiretroviral therapy (cART) significantly impacts the prognosis of individuals infected with human immunodeficiency virus (HIV). Our previous studies have indicated that the baseline CD4 + T cells count and percentage before cART initiation are predictors of immune recovery in TB-negative children infected with HIV, with TB co-infection potentially causing a delay in immune recovery. However, it remains unclear whether these predictors consistently impact immune reconstitution during long-term intensive cART treatment in TB-negative/positive children infected with HIV...

This study reported a case of early-onset parkinsonism associated with a novel variant of the PLA2G6 gene. The boy first started showing symptoms at the age of 11, with gait instability and frequent falls. As the disease progressed, his gait instability worsened, and he developed difficulties with swallowing and speaking, although there was no apparent decline in cognitive function. An MRI of the head revealed significant atrophy of the cerebellum. The initial diagnosis for the boy was early-onset parkinsonism, classified as Hoehn-Yahr grade 5...

OBJECTIVE: Data evaluating timeliness of antibiotic therapy in Clostridioides difficile infections (CDI) are not well established. The study's purpose was to evaluate the impact of time-to-CDI treatment on disease progression. METHODS: A case-control study was performed among hospitalized patients with CDI from 1/2018 to 2/2022. Inclusion criteria were age ≥65 years, first occurrence, non-severe CDI at symptom onset, and CDI treatment for ≥72 hours...

Thiazide and thiazide-like diuretics (thiazides) belong to the most frequently prescribed drugs worldwide. By virtue of their natriuretic and vasodilating properties, thiazides effectively lower blood pressure and prevent adverse cardiovascular outcomes. In addition, through their unique characteristic of reducing urine calcium, thiazides are also widely employed for the prevention of kidney stone recurrence and reduction of bone fracture risk. Since their introduction into clinical medicine in the early 1960s, thiazides have been recognized for their association with metabolic side effects, particularly impaired glucose tolerance, and new-onset diabetes mellitus...

BACKGROUND: We describe a 42-year-old patient with reported "shaking" vision referred due to concerns of possible vestibular system dysfunction. The patient has known history of Usher syndrome type I, bilateral cochlear implants, and severe vision impairment. PURPOSE: This case describes an unusual nystagmus previously only reported in individuals with central demyelinating disorders, significant light deprivation, or in congenital / early-onset visual pathway impairment...

BACKGROUND: Adolescence coincides with a dramatic rise in the onset of psychiatric conditions including depression. Depression symptoms may be particularly prevalent and impairing for youth with autism spectrum disorder (ASD). While prior research suggests adolescence is associated with worsening depression symptoms for typically developing (TD) and autistic youth, it is unclear if they follow a similar course. METHOD: The study examined the trajectory of depressive symptoms in autistic and neurotypical youth over a 4-year longitudinal study using linear and logistic mixed effects models...

BACKGROUND: Oropharyngeal dysphagia (OPD) can be functionally debilitating in persons with multiple sclerosis (pwMS). OPD induces alterations in safety and efficiency of food and/or liquid ingestion and may incur negative sequalae such as aspiration pneumonia or malnutrition/dehydration. Early detection and timely management of OPD in pwMS could prevent such complications and reduce mortality rates. Identifying risk factors of OPD relative to its onset or repeat manifestation will enable the development of care pathways that target early assessment and sustained management...

OBJECTIVE: Colorectal cancer (CRC) incidence is rising among adults under the age of 50 (early- or young-onset CRC). This population is more likely to have advanced-stage disease at diagnosis, suggesting their diagnostic pathway may be prolonged. To better understand factors influencing this pathway, this study explored patients' experiences of decision-making during a diagnosis of young-onset CRC. METHODS: Semi-structured interviews were conducted with 17 participants with young-onset CRC diagnosed in 2021-2022 in Victoria, Australia...

Our aim was to investigate probable biomarkers specific to immune-related central nervous system toxicity (CNST) in cancer patients treated with immune checkpoint inhibitors (ICI) by analysis of 18 F-FDG PET/CT images. Methods: Cancer patients receiving ICI treatment were enrolled in a multicenter observational study that analyzed regional metabolic changes before and during CNST onset from January 2020 to February 2022. In 1:1 propensity score-matched pairs, the regional SUVmean of each bilateral brain lobe of CNST patients (CNST+) was compared with that of patients who had central nervous system infections (CNSIs) and patients without CNST or CNSI (CNST-)...

Background During the COVID-19 pandemic, global trends of reduced healthcare-seeking behaviour were observed. This raises concerns about the consequences of healthcare avoidance for population health. Aim To determine the association between healthcare avoidance during the early stages of the COVID-19 pandemic and all-cause mortality. Design and setting 32-month follow-up within the population-based Rotterdam Study, after sending a COVID-19 questionnaire at the onset of the pandemic in April 2020 to all non-institutionalised participants (response rate 73%)...

Thromboangiitis obliterans (TAO) is characterized by inflammation and obstruction of small-and medium-sized distal arteries, with limited pharmacotherapies and surgical interventions. The precise pathogenesis of TAO remains elusive. By utilizing the technology of tandem mass tags (TMT) for quantitative proteomics and leveraging bioinformatics tools, a comparative analysis of protein profiles was conducted between normal and TAO rats to identify key proteins driving TAO development. The results unveiled 1385 differentially expressed proteins (DEPs) in the TAO compared with the normal group-comprising 365 proteins with upregulated expression and 1020 proteins with downregulated expression...
